Quantifying rates of soil deflation with Structure-from-Motion photogrammetry in west Greenland
Arctic, Antarctic, and Alpine Research, 2018 Aeolian processes are important drivers of geomorphic change in cold regions. Because these processes often occur at slow timescales over large areas, it can be difficult to quantify rates using traditional field methods.

Boreas, Volume 53, Issue 2, Page 227-242, April 2024.Moraine sediments are not easily dated. In this study, different kinds of clasts and boulders were sampled and cored to show that rock surface luminescence burial dating provides correct ages, making it a trustworthy alternative to well‐established methods which might fail at the same site.

A 1500‐year record of North Atlantic storm flooding from lacustrine sediments, Shetland Islands (UK)
Journal of Quaternary Science, Volume 39, Issue 1, Page 37-53, January 2024.ABSTRACT Severe storm flooding poses a major hazard to the coasts of north‐western Europe. However, the long‐term recurrence patterns of extreme coastal flooding and their governing factors are poorly understood. Therefore, high‐resolution sedimentary records of past North Atlantic storm flooding are required.

Perception, history, and science: coherence or disparity in the timing of the Little Ice Age maximum in southeast Iceland? [PDF]
, 2005 In Iceland, studies that integrate local perceptions about the landscape with scientific evidence of change have been few. This article presents a case study from southeast Iceland that has two main objectives.

Lichenometry as Applied to Moraines in Alaska, U.S.A., and Kamchatka, Russia
Arctic, Antarctic, and Alpine Research, 2003 Abstract A selective review of lichenometry as used to date Holocene moraines in five diverse regions of Alaska and in southeastern Kamchatka suggests that growth curves for this North Pacific area may be improved by attention to several factors. These included lichen identification, control point number and distribution, radiocarbon calibration ...

New dating of rapid vertical deformation of Santa Tecla Fault scarps (Mt. Etna volcano, Sicily) by lichenometry method [PDF]
, 2019 The eastern slope of Mt. Etna is characterised by shallow seismicity originating from normal-oblique faulting, Timpe Fault System, related to WNW-ESE regional extension. Recent research has demonstrated that in the fault population of Mt. Etna's eastern

A Review of Lichenometric Dating and Its Applications to Archaeology [PDF]
, 2009 Lichenometry—a method developed by geologists for dating Holocene moraines and other landforms—has many potential applications in archaeology. Maximum-diameter lichenometry can suggest ages for features that were initially lichen-free, such as the moai ...
